Is the bar too high? Foundation settlement in post-earthquake Christchurch
(New Zealand Society for Earthquake Engineering, 2021-04-14)
Three case studies are presented to show how significant ground deformation occurred with the Canterbury earthquake sequence, which in turn resulted in slopes to shallow foundations. The case studies are all from the ...
Evaluation of a geospatial liquefaction model using land damage data from the 2016 Kaikoura earthquake
(New Zealand Society for Earthquake Engineering, 2021-04-14)
Earthquake induced liquefaction and lateral spreading can cause major damage to buildings and infrastructure networks. Common procedures to identify exposed areas such as cone penetration testing require extensive resources ...
Earthquake Stories: Experiences of Building Performance in Earthquakes to enhance future building performance
(New Zealand Society for Earthquake Engineering, 2021-04-14)
The performance of the built environment during earthquakes plays an important role in reducing risk and enhancing the resilience of New Zealand’s urban centres. Although engineering codes and building standards regulate ...
Wall-to-floor connection behavior in a low-damage concrete wall building
(New Zealand Society for Earthquake Engineering, 2021-04-14)
Following the 2010/2011 Canterbury earthquakes, approximately 60% of multi-story buildings with reinforced concrete walls required demolition. Both practitioners and researchers have increasingly realized that low-damage ...
Numerical modelling of a concrete wall-steel frame building
(New Zealand Society for Earthquake Engineering, 2021-04-14)
Buildings that use concrete walls together with steel frames have become increasingly common in Christchurch, with around 35% of post-earthquake buildings using such mixed-material structural systems. This rapid shift in ...
Identifying attributes influencing failure mechanisms in unreinforced masonry buildings using machine learning
(New Zealand Society for Earthquake Engineering, 2021-04-14)
Unreinforced masonry buildings comprise a major part of New Zealand's built heritage and were significantly damaged during the 2010-2011 Canterbury Earthquake sequence. There were 627 URM building assessed in the surveys ...
ATC-145: Influence of prior shaking on earthquake response and repair requirements for structures and elements
(New Zealand Society for Earthquake Engineering, 2021-04-14)
ATC-145 is a FEMA funded project aimed at developing a Guide for repair of earthquake damaged buildings to achieve future resilience. Thanks in part to EQC funding, the project includes substantial New Zealand representation.
To ...
Design of RSFJ Self-centring Brace for Ultimate Limit State
(New Zealand Society for Earthquake Engineering, 2021-04-14)
In previous studies, it was shown that the RSFJ brace assembly is prone to elastic buckling for which a new mechanism composed of two telescopic sections was introduced as a remedy to increase the elastic buckling load, ...
Improvements to state school building design including the implementation of low-damage design criteria
(New Zealand Society for Earthquake Engineering, 2021-04-14)
The Ministry of Education (the Ministry) owns one of the largest property portfolios in New Zealand, with more than 15,000 buildings spread across nearly 2,100 state schools. Following the 2010 Canterbury earthquake sequence, ...
Experimental seismic characterisation of gravel-granulated tyre mixtures and design implications
(New Zealand Society for Earthquake Engineering, 2021-04-14)
Worldwide, due to the large amount of end-of-life tyre (ELT) stockpiles, reusing and recycling of ELTs in civil engineering applications have become a priority, significantly contributing to lessen environmental and health ...
